Due to my having so many bird motifs to show, these are placed into six distinct categories for a better presentation. Ideally, these would be consistent, but due to the nature of the studies, this ideal is not always realisable. Here I have different types, with some finished, some semi-neat. Some are of geometric lines, while others are curved. Some are of a single tile. Some are one-offs. Some are of a specific colouration, namely black and white. There are myriad placement possibilities. I have used my best judgment, albeit well aware of other interpretations, as evinced by previous incarnations of the pages (with nine sections). A brief description follows:
Birds 1 consist of birds of a geometric nature concerning their outline, of one motif (1–8) and two motifs (9–12), all based upon an underlying square.
Birds 2 consists of birds of a geometric nature concerning their outline, of one motif, formed by the process of subdividing a square tile.
Birds 3 features motifs with a natural, lifelike appearance, characterised by subtle, curving outlines that echo the shape of real birds.
Birds 4 consist of tessellations in which the outline consists of both geometric and curved lines, in the form of arcs.
Birds 5—unlike the preceding groupings, which explore tilings composed of various tiles within a theme—focuses exclusively on tessellations based on a single tile: the Greek cross. This also includes variations where the tile is subdivided.
Birds 6. A dedicated section of what I term the 'Pólya tile', specifically of C4, from an illustrated article by George Pólya titled Über die Analogie der Kristallsymmetrie in der Ebene, published in the crystallography journal Zeitschrift für Kristallographie in 1924.
Page History
No recorded date for the text.
16 October 2025. Upgrade from Classic Sites. Much of the text here was outdated, caused by a rearrangement of each page, beginning 9 June 2025. Previously, I had nine sections (and one inadvertent(?) subpage). I have now judged this as somewhat overblown and have reduced the sections to six.
The text is taken from the new heading text on each page.
